PREVIOUS: Clint Eastwood‘s Jersey Boys adaptation keeps filling out the cast of its jukebox musical cast. Deadline hears that Mike Doyle (Shameless, A Gifted Man, Law & Order: SVU) has closed a deal to play Bob Crewe, the music producer who helps mold Frankie Valli and his bandmates into the Four Seasons, in a non-singing role. The real life Crewe is credited as lyricist on the Tony-winning Broadway musical and spearheaded its development alongside original Four Seasons member Bob Gaudio. Doyle’s recent screen credits include the indie Gayby and WB’s Green Lantern. He’ll next appear in You’re Not You with Hilary Swank. He’s repped by Untitled and Gersh.

Taking the role of Nick DeVito is Johnny Cannizzaro (The Muppets, Lost Angels). Nick DeVito is the brother of Tommy DeVito and a founding member of The Variety Trio, the group that began singing together before linking up with Valli and eventually becoming the Four Seasons. Cannizzaro is repped by MediaOne Management.

Last month Christopher Walkenjoined the cast as Jersey mobster Gyp Carlo. Filming on the WB and GK Films pic is set to begin in September in LA. Graham King and Rob Lorenz are producing with Valli and Gaudio serving as executive producers.
